Well the coolest present we as guys could get is, you girls

- So first thing you do when you see him, give him, hug and a kiss and say "Happy Birthday Baby!".
For the present part, give him something he will see all the time - which will remind him of you

(Ex: Picture of you two in a nice frame, alarm clock with a cool sound, a tshirt that has something sexy written on it) Basically creative...
I personally love simple presents..
Good Luck with that!
